audiphile power cords


Do upgraded power cords really make a significant difference in sound quality? I have a Jolida 502p that I think sounds pretty good. What do you recommend for a power cord that would make a significant improvement?

Bojack, THE 60s??!! Really!! So nothing has changed in 50 years.
Bojack, I bet you were the old guy ahead of me in the 5 items or less checkout writing a personal check for 1 item of Geritol??

There's really no debate, just try it for yourself. Easy enough ...
Thankyou Tls49 for the correction, I must say though, The Cobalt with top Oyaide IEC and Plug sounds very good on my system, I am Happy with the performance of this power cord, In the world of High-end power cords, That is Rare for me.
Very good post Ralph, interesting to say the least, Oh, by the way, Back in the late 90s, I rented many, many power cords from the cable company that retailed for lots of money, This was for a krell FPB 200, all of them sounded way worse than the stock Beldin Power cord that came with the amp, However, This is 2014, and I decided to try power cords once again, To my suprise, This power cord I have works well, and sounds great, I am sure there is better, But man, at what cost!, cheers to you Ralph.
If I was to replace my fine sounding but hipness challenged cords with Pangeas that cost under 100 bucks, or ZU audio that are even less in some cases, or entry level Shunyatas, would I then reap the benefits of better electron management? My system currently is very quiet, has PS Audio and Pangea power supply tweaks, and seems to sound great. What do I do with the then unused cables? Make jewelry? The notion that I'd borrow expensive stuff and see what matches best with my system has been obviated by my previous experiment with the one high end cord I have...zero difference...meaning my current batch of decent wire is working, or I'm a tim eared bonehed...I may simply ignore the entire exercise and continue to be ovepaid to mix live jazz concerts using unexotic cables...just don't blow my cover.
I have a friend who profoundly claims that wire is wire..... copper is copper and silver is silver, they all sound alike whether it's power cords, speaker cables or interconnects. I asked him what high end cables he has heard. He said none.
If you haven't heard it, you don't have an opinion.

Regarding power cords and the "last 6 feet" argument, I would think if you had some sort of voltage regulation or power regeneration of some sort, you would then reap the benefits of a higher end power cord.

That said, different cables make a difference. Meaning, in my opinion, MOSTLY all cables DO SOMETHING to the signal leaving the component. If you really want to hear what your system sounds like, theoretically speaking, you would use the exact same cables that are inside your components to CONNECT your components. When you place $3,000 speaker cables between your amp and speakers, your aren't "unlocking" hidden information inside your amplifier. Those cables are manipulating the signal to give it added "air" or more "warmth" or whatever. The cables used inside the amp that lead to the binding posts are usually just plain pure copper wires. Remove the cover of your amp and take a look at the wires going to the binding posts. High end cables are tone controls to the "n"th.
